you can't judge mp3 etc, they roll of much earlier due to their perceptual algorithm.
Have a look into a spectrum analyzer!
Also, a CD is rolling of REAL SHARP at 22k due to the Nyquist frequency.

Kind of a general mastering question, but
obligatory Linux screenshots of JAPA are included, I promise.
I've noticed with some professional cd's/oggs/mp3s I have, the high end is rolled
off at around 20Khz.
What makes you think that is due to mastering? Consider the fact that most mics freq
response begins to roll off between 16k and 18k...
